Importance of Payoff Order in the Climate Policy Game
To analyze the climate policy game, the expected outcomes are determined by the ranking of the payoffs for each strategic choice. The crucial aspect is the relative order of the outcomes (e.g., from Best to Worst) rather than their specific numerical values, as this ordinal scale is sufficient to capture the essential features of the strategic interaction.

Evaluating Simplified Models of International Negotiations
When analyzing international climate negotiations by modeling them as a strategic game between two large countries, what is the most significant analytical limitation of this simplified approach?
Components of a Climate Negotiation Game
The primary value of modeling international climate negotiations as a two-player game (e.g., between the US and China) is to accurately predict the precise numerical economic impact of their policy choices.
Applying Strategic Interaction Models
In a simplified model of international climate negotiations, various real-world elements are represented by specific analytical terms. Match each analytical term with its corresponding real-world element in this context.
Strategic Analysis for a Non-Player Nation
A common critique of modeling international climate negotiations as a simple two-player game (e.g., between the US and China) is that it oversimplifies a complex global issue involving nearly 200 countries. Which of the following statements provides the strongest justification for using such a model despite this criticism?
When international climate negotiations are simplified into a strategic game between two major nations, what is the central insight this modeling approach is designed to reveal?

Figure 4.23b: Two Different Climate Policy Games
Consider a strategic interaction between two countries deciding on environmental policy. For each country, the four possible outcomes are ranked in order of preference: 'Best', 'Good', 'Bad', and 'Worst'. An analyst then revises the model, doubling the numerical value associated with every outcome for both countries. However, the ranking of the outcomes (from 'Best' to 'Worst') remains identical for each country. How does this change in numerical values affect the strategic situation?
Consider a strategic game modeling the policy choices of two countries. For one of the countries, the four possible outcomes are assigned numerical values that correspond to a preference ranking from 'Best' to 'Worst'. Which of the following modifications to these numerical values would fundamentally alter the strategic choices predicted by the model for that country?
Evaluating Strategic Models of Climate Policy
Consider a strategic game modeling the policy choices of two countries. An analyst assigns numerical values to the four possible outcomes for each country, corresponding to a preference ranking from 'Best' to 'Worst'. If the analyst then adds 5 points to every single numerical payoff for both countries, the fundamental strategic nature and the predicted outcome of the game will be altered.

Evaluating Methodologies in Strategic Modeling
Two different strategic games, Game A and Game B, are defined by a country's preference ordering for four possible outcomes. Match each of the following numerical payoff sets to the game it represents.
- Game A Preference Order: Outcome 1 (Best) > Outcome 2 (Good) > Outcome 4 (Bad) > Outcome 3 (Worst)
- Game B Preference Order: Outcome 1 (Best) > Outcome 3 (Good) > Outcome 2 (Bad) > Outcome 4 (Worst)
Two analysts are modeling a strategic interaction between Country A and Country B. Each country can choose one of two actions. The analysts create two different models, shown below, with different numerical payoffs. The first number in each pair is the payoff for Country A, and the second is for Country B.
Model 1 Payoffs:
Country B: Action 1 Country B: Action 2 Country A: Action 1 (10, 10) (0, 15) Country A: Action 2 (15, 0) (5, 5) Model 2 Payoffs:
Country B: Action 1 Country B: Action 2 Country A: Action 1 (100, 100) (20, 120) Country A: Action 2 (120, 20) (60, 60) Based on a comparison of these two models, which of the following statements is correct?
